Random interleaver design in Turbo coding for Digital Magnetic Recording channel

Turbo codes interleaver logic is analyzed in Digital Magnetic Recording (DMR) Partial Response (PR) channels environment. The performances of turbo encoding/decoding process are estimated, in the presence of appropriate DMR noise, generally a particulate noise, manifested as burst errors of various intensities and dimensions. Depending of interleaver, turbo code performance (Bit Error Rate BER) is estimated, in presence of noise, over variations with its parameters. Optimal code length and structures design recommendations are obtained, related to required recording densities and Signal Noise Ratio (SNR) ranges.
